Definitions

  • the invention relates to a water filter device for domestic use.
  • Water filtering or purifying devices for domestic use in the prior art are connected to the municipal water supply, from which they take water to be purified and comprise at least a filter element, for example a reverse osmosis element.
  • the devices are able to remove noxious substances from the water such as aluminium, arsenic, chlorine, lead, sulphates, bacteria, viruses and others, providing, starting from the entering water, purified water suitable for food use and for drinking, while a further and unpurified portion of the water is discharged.
  • plants of this type are complex and expensive, partly due to the required installation and connect-up procedures to the municipal water supply.
  • the aim of the present invention is to obviate the above-mentioned drawbacks, by means of a water filter device for domestic use which does not require connection to the municipal water supply.
  • a further aim of the invention is to free the water filter device from the municipal water supply such as to render it portable and autonomous.
  • a water filter device for domestic use comprising a supply line of water to be filtered, at least a filter means, a line for collecting the filtered water and a discharge line of the water to be discharged, characterised in that the elements are associated to a portable pack which further comprises a container tank (1) for the water to be purified and a pump (2) which removes the water from the tank (1) in order to supply the device.
  • the filter means can comprise at least a reverse osmosis element.
  • the device of the invention exhibits the evident advantage of being autonomous, i.e. unhitched from the municipal water supply, and can thus be portable and used also externally of the domestic environment, for example in a second or holiday home, or in another location.
  • Figure 1 illustrates a water filter device for domestic use of the present invention, denoted in its entirety by 10.
  • figure 1 shows a tank 1 for water to be purified, from which tank 1 a pump 2 accesses the water and supplies a sediment filter 3 and a charcoal filter 4.
  • the water to be filtered is then passed through a reverse osmosis filter 5, from which a first line leads the water to cross a charcoal filter 6. After passing through the charcoal filter 6 the water reaches a potable-water tank 8 ready for use, while a second line, exiting from the reverse osmosis filter, leads the water to be discharged, which after having passed through a flow reducer 7 is deposited in a special tank 9.
  • the functioning principle of the reverse osmosis filter is of known type in the art and for the sake of simplicity will not be further illustrated, its being sufficient to mention that it is based on a membrane the pores of which are so fine as to allow only the water molecules to pass through, while retaining all the larger molecules.
  • FIG. 2 illustrates a variant of the water filter device, denoted by number 20.
  • a ceramic prefilter 18 containing live charcoal is supplied, followed by the reverse osmosis filter 5, from which a first line leads, taking the water to cross a further charcoal filter 15 and a UV ray lamp filter, after which the water is sent to the potable water tank.
  • a second line leading from the reverse osmosis filter 5 takes the discharge water to a flow reducer 7 and thence into a waste tank 9.
  • FIG. 3 shows a further variant of the water filter device of the invention, denoted by number 30.
  • a ceramic charcoal prefilter 18 is supplied, followed by a first reverse osmosis filter 5.
  • a first line leads from there to a check valve 19, after which it takes the water towards a further filter element 21 which can be a charcoal filter or a UV lamp and thence to the potable water tank 8 for use.
  • a second line 25 leads from the first reverse osmosis filter 5, taking first discharge water which is supplied to a second reverse osmosis filter 35.
  • a first line leads from the second reverse osmosis filter 35, which first line joins with the line exiting the check valve 19 and thus sends the water through the filter element 21 in order to reach the potable water tank 8, while a second line exiting from the second reverse osmosis filter 35 takes the water to be discharged, which water, after first passing through the flow reducer 7, enters the waste tank 9.
  • FIG. 4 illustrates a further variant of the water filter device of the invention, denoted by reference number 40.
  • a pair of prefilters 18, 14 are supplied by the tank 1 for the water to be purified, followed by a first reverse osmosis filter 5.
  • the water passes through a flow reducer 41 and takes the purified water from the first reverse osmosis filter 5 towards the potable water tank 8 for use.
  • a second line 25 for first discharge water also leads from the first reverse osmosis filter 5, which second line 25 supplies the water to a second reverse osmosis filter 35.
  • a first filtered water line leads from the second reverse osmosis filter 35, which takes the water to the potable water tank 8, while a second line exiting from the second reverse osmosis filter 35 takes the water to be discharged, which after having crossed the flow reducer 7 enters the waste tank 9.
  • FIG. 5 shows a further variant of the water filter device of the invention, denoted by reference number 50.
  • the tank 1 for the water to be purified is supplied first to a ceramic charcoal prefilter 18, or, in a further and preferred embodiment, to several prefilters located in succession, and thereafter to the reverse osmosis filter.
  • a first line leads from the reverse osmosis filter or the ultra- or nano-filter element 5', which first line takes the water through an optional further charcoal filter 15, and then to a UV ray lamp filter 21, after which the water passes into the potable water tank 8.
